This sudden crisis in relations may be unexpected but it culminates a process that has developed over decades. Pakistan is one of several Muslim-majority countries (Yemen is another; Turkey is becoming a third) where the U.S. government basically lacks any friends.

Obama and Zardari – allies no more?

Although such a situation severely limits American options, here is a realistic policy recommendation that serves American interests:

Give up on the pretense that the two governments are allies and treat Pakistan — with its many madrassahs, its Islamist military leadership, and rogue intelligence service — as a danger zone. Adopt a policy of containment vis-à-vis the Islamism coming out of it, rewarding cooperation and punishing hostile acts. This approach permits Washington flexibly to collaborate or confront as circumstances warrant and needs change.
